Be it kn own that I, LEON APPERT, a citizen of the French Republic, residing at Paris, in the Department of v the Seine, France, have invented a new-and useful Improvement in the Manufacture of Glass with Metallic Netting Embedded October 19,1893, No. 233,528, and inGe'r- Vmany October 30, 1803, No; 81,426,) which improvement is fully set forth in the followint, specification.

, "lhetimportance and poses of glass reinforced bya metallic trellisor network embodied stood and. need not here be set forth. It

has therefore been very desirable to discover I a processwhich while admitting of the production of such article under conditions analogous to those attending themanufacture of and consequently at a moderate price, would preserve all the essentialqualities of limpidity and transparency of the glass without reducing its resistance or increasing itst'ragiIity. Attempts in this direction were made in 1886, when it was proposed to place a metallic trellis or net workibetween two glass plates and'unite the latter,

u .That attempt, however, was unsuccessful, as the product possessed neither homogeneity DOIOOIIOSlOIl. In 1892 it was proposed to obtain the-desired result by forcing into the bodyof molten glass a metallic networker trellis The chief difficulties attending this process wires (such'asit is very, important to use, so

as not to impair the essential propertiosof transparency and limpidity) could nbt be forced in that manner into the body of the glassand that it is not easy uniform sheet. s

. To satisfy the various conditions which this nanufacture requires, it is necessary, first,- hat the metallic trellis glass paste in a regular manner and at such listanco from the surface of the-sheet as may )0 determined upon beforehand, and, "seean}, thata trellis with wiros'as thin as possi ylc'and-with a vcr "large mosh should be ein distance from the Germany October 30, 1893,11'0. 81,426.

The object of the present invention is .to acprogressive formation of two layers of molten tween them of the metallic-trellis or network uniform, and homogeneous body or sheet. The simultaneous formation of the two layers", with the fabric inclosed between them, and

As soon as the optime of pouring shall not ride over it. This 608,096 r r a roller F also receives movement of rotationsuitable distance from the table, so that the .1 Work, said apparatus comprising pressurede glass passes underneath it in the form of a sheet, into which the first cylinder embedsthe netting, as before stated, while bringing thelayer to its final thickness.

.In some cases it may be advantageous in order to prevent the bulgin g of the metallic trellis to press'it against the roller B by means of a small roller G, as shown in Fig. 7.

The invention obviously is notlimited to the use of the precise apparatus described,

since the'principlethereof may be applied in various ways; nor-is it limited to theproduction of smoothed surfaced sheets, since the latter may have impressed thereonin the process of manufacture designs in intaglioor rilievo on one or both sides.

What I claim asmy invention is?- p 1. The process of making sheets of glass with a'metallic trellis embedded thereimsaid process consisting in pourin' g and rolling out a layer of glass simnltaneously.-applying-the trellis to the surface thereof, pouringa'secend layer. of. glass: upon the trellis and rolling the same, the operation being carried on. progressively, substantially as described.

3. The combination with the table upon which the sheet of glass is to be formed, of

pressure-rollers for forming simultaneously several layers of glass, the periphery of the.
